Z'o all whom t map/.concerm Be it known that I, FRANK E.UGENE1BAILEY, a citizen of the UnitedI States,residingatt Philadelphia, in the countyof: Philadelphia. and State of Pennsylvania,thave inventedaa.-

new and useful Improvement inzOilfPurifiers, of which the followingisa-specification..

My invention relates-to. improvements ,int oil purifiers, of that class, especially; de-.t signed to reclaim wasteoil by cleansing,,itof

sediment and other impurities-.t It also furnishes, incidentally, a receptacle andcleanser of new oil, as Well. It isqadaptedto all uses of oil which is fed on the bearingsofengines and other machinery and is then collected in drip pans or other devices, from which it can be conveyed to the oil purifier and being there cleansed of residue matter, made lit for further use as before.

The operation of feeding, collecting, purifying and again returning the oil to bearings may be made automatic by the continuous return system of oiling machinery, in conjunction with this purifier. This system applies particularly, and with much saving of labor, to such establishments as electric light plants, railway stations, power stations, breweries, ice, and refrigeratingplants. and mills, where large machinery is employed; doing away with oil cups on the bearings; the oil being conducted from the purifier, through suitable main pipes and branches to each bearing, from which it drips into suitable receptacles leading into a return system of pipes in connection with a suction pump by which it is returned into the purifier for filtration. v

Iwill now describe the process by which the oil is filtered or cleansed of impurities in my purifier; reference being made to parts of same by letters on the accompanying drawing which shows a vertical section throughthe center.

The body of the purifier is, by preference, cylindrical, made, usually, of sheet iron. The upper compartment a has a sloping bottom a out of and down from which leads the centrally attached pipe b.' Above this sloping bottom is a fine mesh screen or sieve y; while just below this sloping bottom is a partition head k into which are fastened the slightly projectinguppervr ends of pipes e, e, e', e. The: lower endstof pipes e, efasten. through `'the' upper.: head of chamber d. The lower ends ofpipes ef, e', which are perforated, ,hangt-.freeY just above the bottom head of puritier. Theldirty oil whichis'tobe purified islpoured. inwupon the sieve-y, which interceptsany.strawssticks, o'r waste, and passingy through Vruns dow-nthe sloping head a into-the large .vertical pipeb, emerging thence 'intothe lower chamber d. Within this pipe band chamber dit comes into contact with the steam heating, pipes fa-', whoseyinlet connection is at valve n and outlet at valve u. The eect of this contact is to limber up or thin out the oil by separating its molecules and causing any heavier suspended residue matter to be precipitated to the bottom of lower settling chamber d, from which point said residue matter can be taken out by removing the reducer. head t. The oil, now thinned and lightened by parting with its residue, and pressed upon by the column of heavier oil in pipe b, is forcedup the pipes e, e, and overiiows at the top ends upon the upper partition head 7f3-(this forming an upper settling chamber)where it spreadsjout, and partly cooling, allows a further settling. The surface of this thin layer of oil, mounting over the upper ends of pipes e', e', descends thereby and discharges at 'the lower ends and through the perforations in pipes e', e', by which it is divided into small particles, enabling it to be more thoroughly washed in its passage upward, from this point, through the Water in space c. The oil, is iltered and cooled, gradually accumulates above the water line t', and may be drawn off for use, as needed, through the cock q.

l If the continuous return system of lubrication is to be used, the main supply pipe thereof Will be connected to purifier at p, and the return from pumps at m. When new oil is added to that already in the purifier, it is introduced through the funnel Z, which is proa vided with a fine mesh4 sieve or strainer y', and falling upon the partition head le follows the same course as the purifying oil from this point. The cock o is to draw oft the thin layer of sediment or oil, as required, fro m partition head la; the cock r to empty the vessel of water, and cock s to draw oft any remaining oil through small bent pipe w, before removing the reducer head t for final cleaning.

The glass gages h and g are to denote the height, respectively, of the water and oil in tank.

The steam connection at valve 'a may be to either live or exhaust steam.

1 am aware that, prior to my invention, oil purifiers, having Water therein and using heat as a purifying medium, were in use. l do not claim originality in this; but

What I do claim as my invention, and desire to secure by Letters Patent, is"

l. In an oil filter, the combination with an outer shell or casing an upper compartment a, a centrally inclined bottom to said compartment, a screen y placed over said inclined bottom, a lower compartment d, a Vertical pipe b connecting said compartments, a horizontal partition 7c below said bottom ct forming a settling chamber, a filtering compartmentf below said partition, Vertical pipes e connecting compartment CZ with said settling chamber, pipes e suspended in said partition 75 and forming outlets from said settlingr chamber into said filtering chamber extending to a point adjacent to the bottom of said filtering chamber, an inletm to said compartment a, and outlet pf'rom said chamberfand an outlet waste pipe w from said chamber d, substantially as described.

2. In an oil filter an outer shell or casing, an upper compartment a, a centrally inclined bottom a', screen y placed over said inclined bottom a lower cylindrical compartment cl, a vertical pipe b leading from said upper.com partment to said lower compartment, a horizontal partition 7c below said inclined bottom ct forming a settling chamber, a filtering compartmentf below said partition, vertical pipes e connecting said compartments d and said settling chamber, Vertical pipes e forming outlets from said settling compartment into said compartment c and extending to a point adjacent to the bottom of said compartmentf, perforations surrounding the bottom of said pipes e steam pipes m entering compartments a, a funnel Z establishing com munication between compartments a and 7a, a screen y in said funnel, an inlet connection to said chamber a, an outlet connection from said chamberfand a waste outlet from chamber cl, substantially as described.
